method

Advance the underlying RNG as-if delta draws have occurred.
Parameters: |

Returns: |
|
Advancing a RNG updates the underlying RNG state as-if a given number of calls to the underlying RNG have been made. In general there is not a one-to-one relationship between the number output random values from a particular distribution and the number of draws from the core RNG. This occurs for two reasons:
Advancing the RNG state resets any pre-computed random numbers. This is required to ensure exact reproducibility.
